To all whom it may concern:

Be it known that we, PETER R. KRAMER. and GEORGE E. WILsoN, of Stillwater, in the county of .Washingtom State of Minnesota, have invented oertsin new and useful 1inprovements in Bend-Cutters and Feeders, of which the following is s specification.

This invention relates to improvements in band-cutters and feeders for provide a bend-cutter and feeder with three governors, the rst starting the feedin mechanisrn when the threshing-cylinder es etteined the desired speed, the second regulating the movement of the endless grain or bundle cerrier and causing seid carrier to be driven et e fest or slow speed, es may be rcquired to handle the amount of grain that is in position to ass under the threshing-cylinder, and the t ird being arranged in connection with and governing the action of sretarding device placed near the cylinder, so as to control the grain as it asses to seid cylinder.

Another object of the invention is to provide Ineens for adjusting the cutters toward or from the bundle-carrier.

The invention consists generally in the constructions and combinations hereinafter described, and particularly pointed out in the claims. I Y

In the accompanying drawings, forming part of this specification, Figure l is e side elevation of a bend-cutter and feeder ernbodying our invention. Fig. 2 is e. longitudinal vertical section of the same. Fig. 3 is s. plan section online 3 3 of Fi 2. Fig. 4 is s. side elevation showing the and-cutter end feeder elevated `for the purpose of permitting access to the threshing-cylinder. Fig. 5 is it transverse section through the bundle-carrier on line 5 5 of Fig. 2, showing the position of the knives in relation to said carrier. Fig. 6 is e transverse section on line 6 6 of Fig. 2, partly broken away and showing the clutch mechanism in connection with the shaft for driving the carrier.

Fifr. 14 iso transverse section on ine 14 14 of l* ig. 2 through .the shafft, by which the carrier is operated. Figs. l5 and 16 are details of a portion of the mechanism for changing the speed of the cerrier, Fig. 16 being e section on linc 16 16 oi Fig. 14. v Fig. 17 is a partiel side elevation similar to that shown in Fig. 1 with s. part of the mechanism omitted.

General factores-In ell of the di'swings, 2 representse portion of thofmme of e threshing-machine provided with the usual cylinder 3 and concave 4. The immo of the band-cutter and feeder consists of two parts 5 and 6, hinged together at 7 and pivotnlljgVT supported es e whole et 8 upon the braces 9 and 1G, secured to the from@ of the threshingmechine. This construction permits thc outer portion of the frame to befolded under the inner portion in a manner well understood in this class of machines and also permits the entire frame to he turned upon its pivot, so as to reise the in'ner end of thc freine to the position shown in Fis. thereby ermitting access to the threslling-evlinder. llvhen in position for use, the feeder-ironie locked to the frame of the threshing-ninemsn by the bolts 9. Th'e frames 5 and src pro# sided upon each side Where the come toether with the metallic frames 11 and 12, see Figs. 1 and 4,) and the parts of the freine are adapted to be locked in position by the spring-controlled latch 13.

he min generose-The s hsft of the threshing-c linder is provided with a pulley 14, and a elt i5 extends from this pulley around s. pulley 16 upon o. shaft 17, that cerries the band-cutting knives. A belt-tightener pulley 18 is mounted in e pivoted erm 19 and beers upon the belt l5, heingheld sgeinst said belt with a yielding pressure by a. s ring 20, surrounding a. rod 21, having o ne endpivotolly connected to the arm 19 and its other end engaging a. ststionary'lug or erin 22. The pulley 16 is {ixed upon the shaft l?,

preferably by means of s. suitable key or s line, and a. disk 23 is also fixed u on said shaft so es to rotate therewith. ounted looselr u on seid shaft is a. disk 24, provided u'po'n its heb with e. sprocket 25 and having the bundle-carrier.

also a rim or inturned flan e 26. Pivoted arms 27 are secured upon t 1e disk 23, and said arms have connected to them the friction-blocks 2S, adapted to engage the inturned flange 26 upon the disk 24. The arms 27 are connected by the rod 29, and each of said arms is provided with an adjustable weight 30. One of the arms 27 is provided with a lug that extends through a slot inthe disk 23 and is` connected to a spring-controlled rod 31. This spring tends to hohl the blocks 28 out of engagement with the flange 26 upon the disk 24. iNhen the pulley 16 and disk23 are rotated, the weights 30 tend to move outward under the influence of centrifugal force, and when a sufficient speed is attained the tension of the s ring upon the rod 31 is overcome, and the b ocks 2S are forced against the rim or iuturned flange 26, causin f the disk 24 to d,move with the pulley 16 anff disk 23, and thereby to drive the mechanism that is connected to the sprocket 25. (See Figs. 7 and 8.)

The fcnfifeadjuster.-The shaft 17 is mounted at each end in a sleeve 32, that is supported upon a pivoted lever 33. (See Fig. 17.) The opposite end of each lever 33 is pivoted upon the frame 5, so that the ends ol' the levers which carry the shaft 17' are capable of being raised or lowered, and thereby bringing said shaft 17 nearer-to or farther from The shaft 17 carries the knives 35, which may be of any usual or preferred construction. The levers 33 also carry the upright arms 36, that support the crossbar 37 and the series of knife-guards 3S, which extend around the hubs of the knives and are connected by the cross-bar 3Q. The guards 3S are preferably formed of spring metal and serve to keep the straw and un threshed grain from winding around the hubs of the knives. (See Figs. 2 and 5.) For thc purpose of ad'usting said knives we prefer to provide a shaft 4l), passing through the frame of the machine below the bundle-carrier and provided with the cral'ik-arms 41. liods 42 connect the crank-arms 4l with the levers 33. (See Fig. 17.) An adjusting bami-level' 43 is secured upon thf` end ofthe sha ft 4t), and this lever is provided with a catch 44, adapted to engagea segmental rack 45. (Sec Fig. l.) By means of the lever 43 the levers .'43 may be raised or lowered, aud thereby the knives may be adusted and brought nearer to or carried fart 1er away from the lunulle-carrier. Suitable springs 46 are also connected to the levers 33 and to the frame of the machine,

and said springs tend to lift the levers 321 as' soon as the catch 44 is released. From the sprocket 25 u on the hub of the governordisk 24 all of t ie parts ofthe mechanism are driven. 'Fliese parts consist of the endless carrier for moving the bundles forward to the band-cutter and to the threslling-cylinder` the gram-retarder .by which the feeding of the gram to the cylinder is regulated, the vibrating )an by which the heads of the grain broken from the straw and other fine material are fed to the threshing-eylinder, and the rotating beater by which the grain as it leaves the endless carrier is moved downward to the threshing-cylinder.

ill/eens for driving the bumllc-racrfier.-As already stated, we provide means whereby the lmndle-carrier may be driven at a fast or slow speed, determined by the amount of 'grain that has been carried forward and is in position to pass to the threshing-cylinder. One of the levers 33 carries a stud 47, u io'n which is mounted a sleeve having secure to `it a sprocket-wheel 48 and a sprocket-wheel 4Q. (See Fie'. 6.) A,sprocket chain 5U ,passes from t ie sprocket 25 on the shaft 17 around the sprocket-wheel 48 and drives said Wheel and the sprocket 4E). A chain 51 passes from the sprocket 49, engages first a sprocket 52 on a transverse shaft 53, then a sprocket-wheel 54 on the shaft of the revolving beater 55, and then a sprocket-wheel 56 on the shaft 57 of the lmndle-carrier 58. The shaft 53 )asses through the frame of the machine and is provided at its oliposite end from that carrying the sproeketswheel 52 with thc s )rockets 59 and 6U. A chain 61 connects Ithe sprocket 6() with a sprocket 62 on a clutch member 63 on the shaft 57. The clutch member 63 engages a second clutch member 64 on the shaft 57. A hell-crank lever 65 is mounted in a bracket 66,secured to the frame of the machine and having a forked cud engaging tht` movable clutch member 63. A rod 67 is connected to the other end of the bellcrank lever and the opposite end of the rod is connected toa crank-arm 68u11 a transverse shaft 69. A spring 7() surrounds the rod 67 and bears on one arm of the bell-crank level' 65 and tends to hold the two members ol' the clutch in engagement with cach other. :t rod 71, mounted` in supports 72 on the side ofthe machine and provided with an adjusting-nut 72', has an inturned end through which the rod 67 passes and which bears upon the spring 70. ltv this means tlu` tension of lhc spring may be adjusted. 'lhe shaft 69 carries a number of rods or fingers 73, (see lfig. 2,) which project over the bnlulle-carrier 5S. `Ordinarily the bundle-carrier will be driven at the normal speed through the chain 61 and tht` connected parts above described. Sbould, however, a larger amount of grain than can conveniently be taken care of by the cylinder be brought forward by thc carrier, the rods or fingers 73 will be raised by the grain, the shaft 69 will be turned, and through thc described connections the clutch will be disconmcted. The carrier would not stop except for the connection with the opposite end of the shaft 57. This shaft has secured to it a flanged hub 74 and a sprocket 75. 'lhis hub is provided with the projections 76,

inner end to a forked arm 6, that is ivoted on the feeder-casing. The outer en of the board 6 is straddled by a fork 7', pivoted at its lower end on the bundle-carrier frame and lield in place with respect to the board by a suitable stop 7". When the board is raised and turned back over the feeder-casing, the fork 7 will swing down below the carrier out of the path of the grain.

We do not limit ourselves to the details of the construction herein shown and described, as the same` may be varied in manv particulars without departing from our invention. With our band-cutter and feeder the bundles are moved forward, the bands are cut,and the grain is delivered evenly and regularly to the threshing-cylinder, which insures perfect threshing.
